COVID-19 Vaccine FAQs

Show All Answers

1. How effective is the COVID-19 vaccine?

There are multiple COVID vaccines at various stages of the development, approval and distribution process. These include Pfizer-BioNTech (Comirnaty), Moderna (Spikevax), Johnson & Johnson, and Novavax. Clinical trials for the vaccines show that they are safe an effective. Those who are vaccinated, if they do get COVID, are extremely unlikely to get a severe enough illness to require hospitalization or become fatal.

As with other vaccines, the more people who get immunized, the greater the community-wide protection against the disease.

2. Is the vaccine safe?

While the COVID vaccines are relatively new, the clinical trials and vetting vaccines go through are not. The speed of the vaccine development process may make people wary, but there have been multiple layers of safety and quality assurance. As was the case for other vaccines in the past, oversight and review of the COVID vaccine authorization process by the FDA and CDC was led by panels of independent experts. Washington was also a member of the Western States Pact, which created the Scientific Safety Review Workgroup for another layer of scrutiny and expert review to this process. 

3. What are the side effects from the vaccine?

Side effects that have been reported with the COVID-19 vaccine include:

• Pain, redness or swelling at the site of injection
• Fatigue
• Fever
• Headache
• Muscle or joint pain
• Chills
• Nausea
• Swollen lymph nodes

Side effects may occur the day after vaccination and are normal signs that the vaccine is working. You can take fever or pain relievers like acetaminophen or ibuprofen if needed or apply a cool compress to the injection site. Contact your healthcare provider if you are concerned or if the symptoms don’t go away within two days (48 hours).

4. What adverse reactions were reported for the vaccine?

There is a remote chance that the vaccine could cause a treatable but severe allergic reaction called anaphylaxis. This was not observed during the clinical trials, but has been observed very rarely following the first doses of some COVID vaccines, at extremely low rates that are comparable to those of other vaccines. Anaphylaxis usually occurs within 30 minutes after getting a dose of the vaccine and most persons with anaphylaxis have a prior history of allergies or allergic reactions, including some with previous anaphylaxis events;

• difficulty breathing
• swelling of your face and throat
• a fast heartbeat
• itching
• hives
• dizziness and weakness.

Prior allergy or anaphylaxis is not a reason to avoid vaccination, though. Only allergy to the COVID vaccines themselves or their ingredients are a reason to not get vaccinated. Vaccination sites are prepared to handle this reaction and observe patients for an appropriate period of time before releasing them. If you have a history of anaphylaxis and are concerned about getting the COVID vaccine, discuss this concern with your health care provider.

If you have a severe allergic reaction, and are not still at the vaccine clinic, seek medical attention or call 911 immediately. The CDC has also created V-safe, a platform for people to share information on their side effects and reactions. All vaccine recipients are encouraged to sign up for this system to provide additional information about the vaccine’s side effects as vaccination is implemented. Learn more at www.cdc.gov/vsafe.

5. Will the vaccine give me COVID?

No. The vaccine does not contain SARS-CoV-2 and cannot give you COVID-19.

6. How do I know if a message or email offering vaccination options is legitimate?

Know how to spot vaccine scams. Remember that there are no pre-payments required to “get in line” for vaccination, vaccines are not available for purchase online, and vaccines must be administered by licensed medical professionals. Turn to your doctor, clinic, or other reliable sources if you are uncertain whether a message or email about COVID vaccine is legitimate. If you receive a vaccination-related communication from someone other than your health care provider, health insurance provider, or employer, you have reason to be suspicious.

You can check back at www.snohd.org/covidvaccine for additional tools to find reliable vaccination options in Snohomish County. These will be added as they become available. 

7. When will I get vaccinated?

Vaccine is now readily available through a number of providers in Snohomish County. To find more information and provider near you, go to www.snohd.org/covidvaccine.

8. Who should get the vaccine?

COVID vaccines are now available to anyone 6 months of age or older. COVID vaccines are strongly recommended for everyone, unless there is a medical reason they cannot be vaccinated.

Tell your vaccine provider about all of your medical conditions. You should not get the vaccine if you have had a severe allergic reaction after a previous dose of the same vaccine or a severe allergic reaction to any ingredient of this vaccine.

9. If I had COVID, should I still get vaccinated?

Yes, when you are eligible to get the vaccine, it is recommended that you do so. We are still learning about COVID. While reinfection appears to be rare so far, it is possible to get COVID more than once. If you currently have COVID, wait until after your isolation period is done to get vaccinated. Talk with your healthcare provider for additional guidance.

10. Do I get to choose which vaccine I get?

Yes, there are multiple vaccine options to protect against COVID. Right now, the Pfizer, Moderna, Johnson & Johnson, and Novavax vaccines have been approved or authorized for distribution in the U.S. You may see the Pfizer vaccine marketed or referred to as Comirnaty, and the Moderna vaccine as Spikevax. The Advisory Committee on Immunization Practices (ACIP) and the Washington State Department of Health have recommended getting one of the mRNA vaccines (Pfizer or Moderna) over the J&J vaccine. All of the vaccines that have been approved or authorized are shown to be safe and effective in multiple rounds of clinical trials. 

There may be a vaccine that is more appropriate for you than another. We encourage you to talk with your healthcare provider to know what is recommended for your circumstances. While you do have the option to watch for availability of the vaccine you want to get, it is best not to wait if another vaccine brand is available sooner, unless you have talked to your doctor and there is a medical reason to avoid a certain brand of vaccine.

11. Once I get the vaccine, can I stop wearing a mask?

Masks still may be required in certain settings, regardless of vaccination status. Please respect the rules of the venue. Masks also are strongly recommended when cases and hospitalization are high in the community. Voluntary masking remains a good option for reducing the spread of illness. 

There is a lot of great information out there on masking, including from the Washington State Department of Health, the Centers for Disease Controls and Prevention, the Department of Labor and Industries, and Governor Jay Inslee. We encourage you to check out those resources.

12. How does the vaccine work?

The Pfizer and Moderna vaccines are messenger RNA vaccines, also known as mRNA vaccines. These are a new type of vaccine to protect against infectious diseases, but they have been known and researched for decades. To trigger an immune response, many vaccines put a weakened or inactivated germ into our bodies. Not mRNA vaccines. Instead, they teach our cells how to make a protein from the virus—or even just a piece of that protein—that triggers an immune response inside our bodies. That immune response, which produces antibodies, is what protects us from getting infected if the real virus enters our bodies later.

The Novavax vaccine is a protein subunit vaccine. Instead of mRNA, the vaccine includes proteins from the virus (not the full germ). Once vaccinated, our immune system learns to recognize that the protein should not be there and builds the antibodies that will remember how to fight the virus if we are infected in the future.

The Janssen (Johnson & Johnson) vaccine is similar to mRNA vaccines. They all use a piece of the virus’ genetic code for a piece of the virus’ outer shell. After getting vaccinated, the muscle cells make that piece of the virus, then our immune systems react to that and remember it for the future if we get exposed, killing the invading virus and stopping the infection. With the Janssen vaccine, however, that piece of the virus’ genetic code is inserted into an adenovirus (think common cold) that has been modified so that it cannot replicate and cannot make you sick. Our cells open up the adenovirus, make the piece of the virus’ outer shell, and the process continues as described above. 

13. Does the vaccine change my DNA or implant a chip?

No. They do not affect or interact with our DNA in any way, and no microchip is present. The genetic code of the coronavirus never enters the nucleus of the cell, which is where our DNA (genetic material) is kept. The cell breaks down and gets rid of the foreign virus’ code soon after it is finished using the instructions.

14. What is in the vaccine?

You may see some rumors about ingredients listed online or in social media. These are generally myths. The ingredients in the Pfizer and Moderna vaccines are pretty typical for a vaccine, as are the ingredients in the Johnson & Johnson vaccine and the Novavax vaccines. They contain the active ingredient of mRNA, adenovirus, or protein subunit along with other ingredients like fat, salts, and sugars that protect the active ingredient, help them work better in the body, and protect the vaccine during storage

15. Where do I find accurate info about the COVID vaccine?

There is a lot of misinformation or disinformation circulating about the COVID-19 vaccines. Reliable sources include your local public health department, the Washington State Department of Health, the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC). If you have specific questions or concerns, please talk through them with a professional healthcare provider.

Information addressing some of the most common misinformation about the COVID vaccines can also be found at www.snohd.org/vaxupsnoco. 

16. Where can I get my COVID-19 Vaccine Record?

You should receive a CDC COVID-19 Vaccine Card at the time you are getting vaccinated. 

The Washington State Department of Health is in charge of maintaining vaccine records in the Immunization Registry known as the Washington State Immunization Information System (WAIIS). Residents are able to access their records through the resident portal to print official COVID-19 Vaccine certificates. For any issues, a hotline specialist can be reached at 833-VAX-HELP. You can also email waiisrecords@doh.wa.gov. 

If you were vaccinated outside of Washington state, please go here for a list of contacts that can assist you in locating your vaccination information. 

17. Do I need a booster?

Boosters can enhance or restore protection that may have decreased over time after your primary series vaccination, or some may be geared toward increasing protection against specific prominent strains of the virus.

Boosters are recommended and you should check to see if you are due for a booster dose. Timing and number of doses may vary based on age, health status and the type of vaccine you received for your primary dose.

Learn more from the CDC about booster doses.
